ABSTRACT:
A sealed case has first and second housing portions. A motor section is arranged in the first housing portion of the sealed case and has a rotating shaft extending in the second housing portion. A compression mechanism section is arranged in the second housing portion of the sealed case and has first and second cylinders stacked on each other and first and second crank portions which are formed on the rotating shaft in the first and second cylinders, respectively. An accumulator is arranged outside the sealed case so as to substantially oppose an arrangement position of the motor section. A first suction pipe connects the accumulator to the first cylinder of the compression mechanism section. A second suction pipe is arranged outwardly from the first suction pipe so as to connect the accumulator to the second cylinder of the compression mechanism section. The second suction pipe has a first coupling pipe having one end coupled to the second cylinder, a second coupling pipe having one end coupled to the accumulator, and adjustment coupling portions for coupling the other end of each of the first and second coupling pipes so as to freely adjust positions thereof.
